SPECIFICATION forming part Vof Letters Patent No. 685,696, aai-,ea october a9, ie'oi.V Application ild J'un'e 15,1901. Se'ial No. 64,695. (No modell) To @ZZ whom it may concern:

Be it known that I, HARRY A. SEYMOURE, a citizen of the United States, residing at'Chicago, in the county of Cook and State of Illinois, have `invented certain new and useful Improvements in Chucks for Making Frames, of which the following, when taken in connection with the drawings accompanying and forming a part hereof, is a full and complete description, sufficient to enable those skilled in the art to which it pertains to understand, make, and use the saine. Y j

This invention relates to the making of' a chuck wherein a stri-p of sheet metal having the ends joined or not joined, as preferred, may be placed and securely held while one of the sides thereof is turned overto form a crowning bead or torus; and the object of this invention is to obtain a chuck of the kind named wherein first one and then the othei` of the side edges of a strip of sheet metal may be turned into a crowning bead or torus and the completed `article obtained thereby-eto wit, a frame for pictures, photographs, mirrors, and other articles-may be taken from the chuck Without crinkling, bending, or other injury to such frame. I find it necessary in making a frame of the kind obtained by the use of this chuck to arrange the frame so that it will be expansihlethat is, so that the frame can be opened to admit the placing of the same over a glass, a mat, a packing, and a picture, photograph,

or other article, or over a mirror and the backing thereof--and to obtain the expansibility required the ends of the stripwhich is formed up to make the frame must be d etachably connected together, and therefore I have sought to obtain a chuck in which a strip of metal maybe `held and the sides4 turned over to form a bead or torus, whether the ends of the strips are secured togetherI l permanently or whether theyY are simply brought together in proper position in the chuck and there held by the chuck While the operation of'turning the side edges over is ;vation of such chuck, partly in section. Fig. ais a view of amodifcation of the'chuck. illustrated inlFigs. Tto 3, both inclusive, on line 4 4 of Fig. 2 viewed in the direction indicated by the arrows. Fig. 5 is a like View ofv an additional modification of the chuck illustrated in Figs. 1 to 3, all inclusive; and Fig. lG is an elevation of the vertical shaft in the modification'illustrated in Fig. 5 and a sectional view of a portion of the bed-plate,l

the hub thereof and parts adjacent to such bled-plate. on line 6 of Fig. 5 viewed in the ldirection indicated by thearrow. Fig. 7 is a detailed view of the element, hereinafter termed a locking-plate, common to all the constructions shownand forming a part of the chuck embodying the invention. Areference-letter applied .to designate a given part is used to indicate such part throughout the several figures of the drawings Wherever the same appears. A is the bed-plate of the chuck. AB isa peripheral rim to the bed-plate A.

C isa hub to bed-plate A, and D is a screwthreaded shaft rotatably mounted in the hub C. The screw-threads d d on the shaftD fit corresponding screw-threads in the hub C, so that as'suchpost is turned it is moved 1ongitudinally. I

E E,Figs. l, 2, and 3, are spring-metal halfcircles loosely resting on the bed-plate. A.

D is a collar loosely fitting on shaft D, and cl is a shoulder on such shaft D, pressing against collar D to force such collar down .With-the longitudinally-downward movement of the shaft as such shaft is turned by the rotationvof hand-wheel d2 through the engagementofv thescreW-threads d with the corresponding screw-threads in hub C ofthe bedplate A. d3 represen-ts screw-threads on shaftD.

E E are spring-abutments yalsoresting loosely on the bed-plate A and against the spring half-circles E E. Spring-abutments E' E are provided with sliding abutments e e. F F F are connecting-links loosely attached, as by the pivots fff, to the collar D' on shaft D and also, as by pivots f'f, to the sliding abutments e' .e/ of the respect-ive spring-abut-A ments E' E'.

IOO

F F are guide-pins in` bed-plate A adj'al cent to the abutments E E at the center of spring half-circles E E-that is, midway between locking-plates H II, hereinafter described.

fzfz are guide-pins passing through springabutments E E', sliding abutments e e', respectively, and into half-circles E E, respectively. (See Fig. 2.) Vhen the post or shaft D is turned, as by the hand-wheel cl2, to bring such shaft longitudinally toward the bedplate A, the spring-abutments E E are thrust outwardly against the half-circles E E by the sliding abutments e' e', and such half-circles are thereby forced against the strip of metal G, Fig. 2, placed around and against the inner cylindrical face of the peripheral rin'l B and between such peripheral rim and such half-circles.

H H are locking-plates fitting between the ends of the half-circles E E and against the strip G. Strip G is held firmly in place by the forcing of the half-circles E E and locking-plates H H outwardly on the bed-plate A against such strip G.

I is a collar fitting loosely on shaft D to move longitudinally thereon, and I is a collar on such post or shaft D, provided with screw-threads t' t', fitting over corresponding screw-threads d3 on such post or shaft D. Collar I has an annular projection on the upper face thereof extending into a corresponding recess at the lower` end of the collar I', and I2 is an annular groove in the upper part of the collar I, into which groove pins I3 I3 extend, such pins thereby connecting collars I I' together, so that rotation of collar I on shaft D will not produce rotation of collar I; but the longitudinal movement of collar I (caused by screw-threads t' in collar I engaging with screw-threads Z3 on shaft D) will produce corresponding longitudinal movement of collar I on shaft D. The collar I is provided with the hand-wheel t", by which it may be turned on the shaft D.

J J are connections loosely attached, as by the pinsjj, to collar I and to the lockingplates H H, respectively. Then the collar I is turned on shaft D, so as to be moved longitudinally on the shaft toward the bed-plate A, such collar I forces collar I toward the bed-plate A, and the locking-plates are thereby forced into contact with sheet metal strip G.

K is a peripheral groove on the lower outer corner of half-circles E E, and 7c 71: are grooves on the locking-plates H H, positioned relative to the bed-plate A the same as are grooves K K.

K is a corresponding groove on bed-plate A adjacent to groove K la.

Lis an annular recess on the top face of bedplate A, into which recess the lower side or edge of the strip Gis placed when such metal strip G is put into the chuck for the purpose of turning or forming the first bead or torus g thereon, and in which annular recess the lower side or edge of the metal strip G remains while the upper side or edge is turned or formed down upon beads e e (on spring-cir-A cles E E) and h h, (on locking-plates H H.)

The metal strip G is shown in Fig. 2 with the bead g and also bead g as turned thereon, and as in this machine first one and then the other of such beads are turned the bead g is illustrated as in the groove or recess formed by K, 7.a, and K', and bead g' is shown as turned down on beads e and 7L of spring-circles or half-circles E E and locking-plates H H, re spectively.

M is a handle on locking-plate H.

When a sheet-metal strip G is placed in posilion in the chuck and secured in place between the cylindrical inner face of peripheral rim B and the periphery of the half-circlesE E and locking-plates H I-I and the upper side or edge is turned over and down on such beads c h, obtaining the crown-bead g, it will be found necessary in order to remove such strip from the chuck to first loosen the locking-plates H H from engagement with the bead of the metal strip. This is done by turning the hand-wheel t" of collar I to move such collar and collar I longitudinally on shaft D away from the bed-plate A. 'When so moved, collar I by means of connections J .I moves or rocks such locking-plates II H on the face indicated by reference-letter 7L' in Fig. 7, thereby simply lowering bead 7L from the position thereof illustrated by full lines in Figs. l, 2, 3, 4, 5, 6, and 7 of the drawings into substantially the position indicated by dotted lines in Fig. 7, thereby releasing such bead it from engagement with the turned-down or formed bead of the strip G. Continued movement of the collars I I' on shaft D away from the bed-plate A will draw such locking-plate II away from contact with the metal strip G and out from between the ends of the spring half-circles E E, say, into substantially the position indicated by the broken lines I-I' in Fig. 7. After the locking-plates H I-I are released in the manner last above set forth the spring-metal half-circles E E may be released from strip G and the turned-down bead thereon by turning the hand-wheel d', and thereby causing the shaft D to move longitudinally away from the bed-plate A. Having turned or formed the bead g on one side or edge of the strip G and having loosened the locking-plates I-I H and spring halfcircles E E, as last above described, the strip G may be taken olf the chuck and turned and,

again placed within the peripheral rim B, with the bead g thereon in the annular recess formed by the peripheral grooves K, K, and 7o, and such strip G is again secured in place by means of the spring half-circles E E and the locking-plates H H in the same manner as before. A second bead g may be turned on strip G similar to bead g. As the manner of the turning of the beads g g' on the side or edges of the strip G and the machine for doing the same form no part of this invention, the same are not herein illustrated or described, the purpose of this invention being IOO IIO

to obtain a chuck wherein strip G may be held rmly while such beads g g are respectively turned or formed and from which chuck the eXpansible frame obtained from strip G by turning the beads thereon, as described, (while the same is held in the chuck,) may be removed without injury to the frame, and when the bead g' has been obtained the frame (strip G, having beads g g') may be removed from the chuck by first loosening the lockingplates I-I H in the manner hereinbefore described (by turning the hand-wheel e" 72') and afterward loosening the spring half -circles by turning the small hand-wheel d2, as hereinbefore'described. The half-circles E E will automatically release from the bead on strip G as the post D is longitudinally moved, by means of the hand-wheel d2 thereon, away from the bed-plate A. The frame so obtained from strip G may be taken from the chuck and a new strip G placed therein and a new frame made therefrom.

The ends of the strip G are preferably attached together while in place in the chuck, as by a common pin or bolt, and N O are recesses in peripheral rim B and one of the locking-plates H to respectively receive the head and nut of such bolt.

Although I prefer to construct the parts E E of spring half-circles with duplicate locking-plates H H, as hereinbefore described, I have made an operative chuck in which I substitute a single spring-ring E2 and a single locking-plate H therefor, as is illustrated in Fig. et of the dra-wings.-

In other respects the construction illustrated in Fig. t is the same as the construction illustrated in Figs. l to 3, inclusive.

In the modification illustrated in Figs. 5 and 6 the three-part ring E3 E5 E3 is substituted for the two-partspring half-circles E E of Figs. l, 2, and 3, and the three lockingplates H H H (triplicates) are substituted for the locking-plates H H (duplicates) of such Figs. 1, 2, and 3. The'collar Dsis also placed on shaft D and secured in place thereon to move longitudinally therewith, (as by setscrew,) so that the collar D is maintained in substantially the same place longitudinally on such post D, and thereby the necessity of constructing the three-partv ring E3 E3 E3 of spring metal is obviated. In other respects lthemoditication illustrated in Figs. 5 and 6 may be constructed substantially the same as the construction illustrated in Figs. l and 8, inclusive, of the drawings.

The operation of the modification illustrated in Figs. 4, 5, and 6 is substantially the same as the operation of the construction illustrated in Figs. 1, 2, and 3.

The half-circles E E, the spring-pieces E2 E2, and the three-part pieces E8 E3 E3 severally constitute what I term a segmental rim, resting on the bed-plate A within the peripheral rim B, such segmental rim being movable in a horizontal plane toward and away from the peripheral rim B, the position of such segmental 4rim with reference to the peripheral rim being determined and controlled by the longitudinal movement of the post or shaft D, and the locking-plates AH when forced between the ends of the segmental rim complete an inner ring, which is pressed or forced kagainst the strip G at the' means to force thesegmental rim outward to contact with a metal strip interposed between such segmental rim and the peripheral rim,

a locking member also on the bed-plate, and means to force such locking member to contact with the metal strip between the ends of the segmental rim, means to retract the seg.

mental rim and means to retract the locking member, such segmental rim and locking member provided with a crowning-bead substantially as described.
